I would go in the garden with a cuppa, or a stiff gin, with a friend or my other half. I'd sit near enough to their open windows and have a loud conversation about how noise travels and did my friend /OH know what I'd heard just the other day whilst in the garden. Go on to explain that you weren't sure if it was badgers or wild pigs or whatever hahaha.
I wouldn't dare do what lemongrove suggested in case they took me up on the offer!
